How to Troubleshoot & Replace Whirlpool AP5956390 / W10756692 Control Board

We replaced the control electric panel. So far washer is working fine. This part was easy to replace. 

After reading about the F11 code, I learned the problem was with either the CCU or the MCU control boards. I replaced the CCU first, however I still received the F11 code. I returned the CCU for a full refund,minus shipping and ordered the MCU. After installing the MCU the washer works great. It was very easy to install and the video provided by AppliancePartsPros was a great help. 

Before finding ApplianceParts.com, I thought for sure I was going to be buying a new washer but that wasn't the case. After watching the video and reading the blogs on how to check the resistance on the motor, I was pretty sure that the MCU was the issue but I wanted to also checked the continuity of the wire harness between the motor and the MCU. One posting even suggested unplugging the connectors to the motor and MCU and plugging everything back in to make sure it is not a bad or loose connection. Neither of those fixed the issue so I decided with the ApplianceParts.com guarrantee, I would replace the MCU first since that is what the resistance test pointed too. I got my new MCU in two days and using the installation video they provided, I had the old one out and the new one in in less than 30 minutes. With the video, I kind of felt like a professional repairman because the repair was so easy. Now that everything was back together, it was time to test it and WOW, the washer was working perfectly again. To replace the washer, I would have had to easily pay $900 but by fixing it myself I look at as I saved more than $600. Thanks ApplianceParts.com! 

Replaced Motor control unit Part number W10756692. WORKS LIKE A CHARM!! 

Problem was intermittent. Using information from repair forums to troubleshoot the problem, I rebuilt wiring harness, tested motor windings and tachometer resistance. Replaced motor control unit. 

After doing some research on-line I Idetermined the Motor Control Unit (MCU) was bad. Ordered a new MCU and replaced the bad one. 

Replaced the motor control unit and so far it is good. Thank you for the quick delivery. Mo. 

Replaced exiting motor control unit with new one. Very easy replacement and IT WORKED!!! 

After some online research, it seemed that a failed motor control unit was the culprit. While our washer is 19 years old, it still works great and I couldn’t see spending $800-1000 to replace it for a part I was capable of installing myself. The video was extremely helpful because the newer generation board had different connection sites, but I got the part installed in about 15 minutes. Washer immediately fired up and ran a cycle with no issues. I’ve also used Appliance Part Pros for parts to repair our Maytag dishwasher and our dryer. We have likely saved THOUSANDS of dollars over the years with some basic tools and a few parts. Thank you! 

I was able to diagnose the problem and order the part via Appliance PartsPro, then installed the part following their video. Very easy and convenient. Saved me from replacing a $1000 washer.
